WATCH: BRITNEY SPEARS Brings Vegas Show To Apple Music Festival!

Britney Spears performed all her biggest hits and turned the London Roadhouse into a Vegas theater for her 90-minute Apple Music Festival gig.

The pop legend gave the audience a taste of her Las Vegas show Piece of Me as she performed all the favorites from her nine albums. Fans were treated to hits like "Baby One More Time", "Oops! I Did It Again", "Stronger", "Crazy", "Womanizer", and a lot more.

Surrounded by her troupe of dancers, Britney also made an impressive eight outfit changes during the fast-paced performance. In fact, she only interacted with the crowd twice before proceeding to her next song. But the pop princess gave everyone a scare when she cancelled a back walkover in the middle of her "Touch Of My Hand" dance routine which was caught on camera.

She later explained in an interview with BBC Radio 1 how she "freaked out" over that incident. The dancer wasn't her usual guy who she had for the past three years. "It was [the new guy's] first time to touch my back, and I couldn't do it... I should have felt more confident, but I didn't," she added.

No worries, Miss Spears. We're just glad you're not hurt. Check out a piece of Britney's performance:
